BITI in plain words
Three months to Sep 11, 2026: BITI returned −19.1% where its own daily promise gave −20.6%, 1.4 points over. Read the multiple against the whole window instead and −1 times IBIT's 21.4% implies −21.4%, which makes BITI look 2.3 points over. 0.9 of that is daily compounding, which happens to any −1 times fund over the same path, and the rest is the fund. BITI aims to return -1 times IBIT's move each day, then resets. Over one day it does that. Over longer, the daily results compound, so the total is not -1 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more. IBIT moved at 38% annualized over that window. That is what decides how far the two figures separate: the same fund on a calm underlying and a violent one is a different product.
BITU in plain words
Three months to Sep 11, 2026: BITU returned +37.3% where its own daily promise gave +42.5%, 5.2 points short. Read the multiple against the whole window instead and +2 times IBIT's 21.4% implies +42.9%, which makes BITU look 5.6 points short. 0.4 of that is daily compounding, which happens to any +2 times fund over the same path, and the rest is the fund. BITU aims to return +2 times IBIT's move each day, then resets. Over longer, the daily results compound, so the total is not +2 times the period's move: in a market that falls and comes back it is reliably less, and in a steady run it can be more.
Questions people ask
- Which came closer to its stated multiple, BITI or BITU?
- Over the window to Sep 11, 2026, BITI finished 2.3 points from what its multiple implies and BITU finished 5.6 points from its own, so BITI came closer. Neither figure predicts the next window: it depends on how much the underlying moves about.
- Are BITI and BITU levered on the same thing?
- Yes. Both are levered on bitcoin, BITI at -1 times and BITU at +2 times the daily move.
- Which one decays faster, BITI or BITU?
- Decay follows how much the underlying moves about. Over this window BITI’s moved at 38% annualized and BITU’s at 38%, so BITI has the rougher ride and, at the same multiple, loses more to compounding.
- Can I hold BITI or BITU for a year?
- Both reset every day, so the multiple in the name applies to a single day and the daily results compound. Over a year the total is not the multiple times the year’s move, and in a market that falls and comes back it is reliably less. ETFIQ makes no recommendation either way.
